' To all whom it may concern: p Be it knownthat I, WILLIAM F. WAUL, a citizen of the United States, and resident of St. Louis, Missouri, have invented 'certain new and useful Improvements in Steam Systems, of which thefollowing is a specification.

This invention relates to improvements in a steam system, and for its object a pipe connection leading from the-steam dome of the boiler orsteam generator, the latent heat from the steam first passingthrough one or a plurality of machines without impairing its expansive properties, the said steam after passing through these several machines being directed in a concentrator tank and-from thence to the engine and the exhaust conveyed to the water heater or back to the boiler as found desirable. .-The most essential and specific feature of my invention is to utilizethe latent heat of live steam before admitting it into the engine without impairing its expansive properties to any great extent.

' The theory of my invention is to pass live steam from the steam generator through one or a plurality of machines where heat is to be utilized thereby using the latent heat then passing the steam through a, concentrator chamber or separator by which any condensation is removed and the. dried steam conveyed to the engine thereby saving a great percentage of fuel in operating a plant, and also dispensing with nearly all of the ex haust.

Figure 1, is a diagrammatic view showing the general connection of my invention.

Fig. 2, is a detail central vertical sectlonal view of the concentrator tank or separator used in connection with my invention.

Fig. 3, is a horizontal sectional view of the same taken on the line 3-3 of Fig. 2, viewing the same in the direction indicated by the arrow.

Referring to the drawing in detail and especially to Fig. 1, 4 indicates a boiler or steam generator which is equipped with the usual steam dome 5 to which is connected a steam pipe 6 which is directed to any convenient place in the premises and to which is connected steam pipes 7, 8, and 9 leading into various machines such as a drier 10, a washer 11 and a mangle 12, these machines being preferably used in establishments such as laundries or the like.

these machines the live steam is 'directed into a pipe 13through the connections 14,

15 and 16. This pipe then terminates into a concentrator or separator 17 which is'pref- 'erably in the form of a drum as that in dicated in Fig. 2,.thepipe13 entering the top as that shown in Fig. 2 and represented by the numeral 18. This drumis also provided with a depending tubular member or thimble 19 of somewhat larger diameter than the end of the pipe 18 extending there in. Into the head of the concentrator, or separator extends the end 20 of thepipe 21, which directs the livesteam into the engine cylinder 22. p This steam after entering the cylinder of the engine permitsthe exhaust to escape through the pipe 23 and is directed into the feed water heater 24: which is of the ordinary construction and is provided with the usual water supply of a cool nature and which is heated by means of the exhaust contacting therewith and from said water heater the heated water is conducted by the boiler.

At the bottom of the separator is connected. a pipe 25 whichleads to a pump 26 andany condensation accumulating in the separatorlis removed therefrom by meansof the pump 26 and forcedba/ck into the boiler through the pipe27 such condensation be ing generallytat a degree of from 280 to 300 degrees Fahrenheit. p

As an additional safe-guard I connect to V 1 p1ped2-5 a Icy-pass 218 provided with a a ve an o era in sai i e leadin in the feed Wa ter hea ter. p p g to To said pipe 25 is also connected a by pass 29 lead ng into a steam trap 30 from whlch the condensation or particles of steam located therein is directed to the feed water heater through the pipe 31.

Such condensation which occurs in the separator is handled by the pump 26 but in the event of a mishap to said pump the condensation may be passed into the feed water heater by means of the steam pressure in the concentrator or separator passing through the by-passes 28 and 29 depending on which one of the two is in operation at that particular period.

The steam trap 30 shown in Fig. 1 and in connection with the system is ordinarily in readiness to be used automatically in the event the pump should be out of order, but

means of pipe injector or the like back into "pipe, epa at r. QW iQh heret r 13,113.? 18

uldhe-s a ee e m w e o ed then the condensation can be handled by means of the pass 28 by located on said pipe.

' Referring to the sectional View of Fig. 2

the concentrator or separator is of such structure as to permit the steam after havmg;w passed: through the various machines to be separated from the moistpre and as it strikes the tubular member or thinrble 19 his W a-palms t e c nd nsati n. to p dWaWa la nw he b t ama ft 'he separ qr and il er; onlyv I? i ame P s Ilt thesend ZQ of the pipe 21.
